MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The .pre-commit-config.yaml references external git repos (https://github.com/astral-sh/ruff-pre-commit and https://github.com/pre-commit/mirrors-mypy) that pre-commit will fetch at install/runtime and execute as hooks, so they are runtime external dependencies that download and run remote code.
